Definitions
- the present invention relates to a method for the preparation of linear alpha-olefins by oligomerization of ethylene in a reactor in the presence of an organic solvent and a homogenous catalyst consisting of a zirconium component and an aluminum component, and a reactor system therefore.
- DE 43 38 414 C1 discloses a method which is carried out in an empty tubular reactor having inlets and outlets for ethylene, oligomerization products and solvent-catalyst mixture.
- the catalytic components are dissolved in the solvent and are introduced into the reactor at a pressure of 31 bar and at a temperature of 40°C.
- a pressure of 31 bar an oligomerization reaction can already take place which may result in plugging of pipes for delivering the catalyst-solvent mixture.
- This object is achieved by a method characterized in that the zirconium component and the aluminum component are pre-mixed in a pre-mixing device, prior to introduction into the reactor, at a temperature range of about 20°C to about 100°C and with a residence time in the pre-mixing device of maximum 75 hours.
- the pre-mixing is carried out continuously in a separate vessel, static mixer, continuously stirred tank or batchwise.
- the solvent is toluene.
- the organoaluminum component is Al(C 2 H 5 ) 3 , Al 2 Cl 3 (C 2 H 5 ) 3 or AlCl(C 2 H 5 ) 2 or mixtures thereof.
- the pre-mixing device is maintained under ethylene pressure of less than 5 bar, preferably under atmospheric pressure.
- pre-mixing is carried out preferably at a temperature of about 50-70°C and with a residence time in the pre-mixing device of about 15 to about 120 minutes, preferably about 30 to about 60 minutes.
- a reactor system for the preparation of linear alpha-olefins by oligomerization of ethylene comprising a reactor and a pre-mixing device connected thereto to pre-mix catalytic components in a solvent, prior to introduction into the reactor.
- the inventive method overcomes the drawbacks of the prior art. Especially, an improved productivity of the oligomerization reactor is obtained, as the preformation of the catalyst is done outside of the reactor. Further, an improved homogeneity of the liquid reaction phase is obtained. Further, start-up and operation of the method is simplified, since the catalyst ratio cannot become wrong within the oligomerization reactor. Also the reactor stability is improved, since a reactor runaway due to over-dosing of one catalyst component is avoided.
- the oligomerization is carried out in an oligomerization reactor 1 having an inlet 2 for introduction of ethylene into the reactor 1, an inlet 3 for introducing a solvent-catalyst mixture, an outlet 4 for removing a mixture of ethylene and light alpha-olefins, and an outlet 5 for removing a liquid mixture consisting of solvent, catalyst, dissolved ethylene and linear alpha-olefins.
- the inlet 3 is fed with the solvent-catalyst mixture from a pre-mixing device 6 having two inlet-lines 7, 8 for separately introducing the catalyst components (zirconium component and aluminum component) into the pre-mixing device 6.
- the rate and amount of each catalyst component may be conveniently controlled.
- the pre-mixing device 6 may be a separate vessel, a static mixer or a continuously stirred tank.
- the pre-mixing may be carried out continuously or batchwise. Further, the pre-mixing preferably performed at a temperature of about 60°C, wherein the catalytic components have a preferred residence time in the pre-mixing device 6 of about 30 to about 60 minutes.
- the catalytic components fed into the pre-mixing device are dissolved in the solvent, preferably toluene.
- the pre-mixing device is maintained under an ethylene pressure of less than 5 bar to avoid an oligomerization reaction therein.
- All materials used for the catalyst were prepared and handled in a glass box filled with nitrogen with less than 1 ppm oxygen and water.
- the catalyst was pre-mixed in a 250 ml round bottom glass flask in a glove box and was stored therein at 20°C from 18-72 hours and then charged into a 2-liter bench scale reactor under nitrogen, whereupon an oligomerization was started at a temperature of 80°C and at an ethylene pressure of 30 bar.
- fresh catalyst was prepared in a glove box at 20°C and then the catalyst was charged into a 2 liter bench scale reactor maintaining the reactor temperature between 40°C-60°C for 15-120 minutes. Ethylene was introduced into the reactor after the predetermined premixing time until the desired 30 bar pressure was obtained and the reaction temperature was held at 80°C.
- the catalytic activity was calculated as the amount of ethylene consumed in one hour. After one hour, the reaction was stopped. A sample of liquid LAO product was collected in a glass veil and analyzed by gas chromatography (GC) at room temperature.
- GC gas chromatography
- Example 1 of table 1 is an oligomerization run utilizing a standard LAO catalyst without premixing of the catalytic components.
- the data of examples 2 to 5 indicate that catalyst aging with time (18-72 hours) has increased the catalyst activity, LAO yield and selectivity. It was found that the pre-mixed catalyst was quite stable during this period as compared to standard fresh catalyst.
- example 10 of table 1 the catalyst was pre-mixed and stored for 30 hours at 20°C in the glove box and was then charged into the reactor, whereupon the reactor temperature was maintained at 50°C for 30 minutes. After that by introduction of ethylene the reaction was started to be conducted at a temperature of 80°C.
- the results of example 10 show that the catalyst activity, LAO yield and selectivity were slightly increased.
